There are new concerns over wearing masks for long periods
Dentists are now saying that wearing masks can dry out your mouth and cause your gums to recede and also create the perfect storm for cavities.
Other Dr's are saying you don't get enough Oxygen because you are rebreathing a good percentage of your exhaled Carbon Dioxide.
Be aware, don't overwear
and don't smoke
You'll light your dam mask on fire
I only wear a mask when I go shopping and, no more than 10 or 15 minutes.
Went out for a drive with my Dad today.
